if one sphere has a mass of 2 kg in electric charge power 4 microcoulomb while another sphere 3 metres away is a mass of 1 kg in electric charge of 5 microcoulomb what is the acceleration of the more massive sphere

Please, how do I find the maximum emf produced in the cycle?

Find out the time at which the potential across the capacitor is equal to that across the
resistor, when switch S is closed at t=0, the capacitor is charged through the resistor.
Consider the value of capacitance of a capacitor= 12mF and resistance of resistor is 25ohm.

determine the shunt of a circuit if galvanometer has a scale of 10ma and a resistance of 3 ohm and current of 1a

An ion-source is at distance d from a flat, horizontal collector at the same potential as the source. A magnetic field of flux density B acts horizontally (Magnetic ild line go from the Left side towards the Right side). The field is uniform throughout the region between the source and the collector.

An ion of charge q and mass m is emitted vertically downwards at speed v. Under what conditions the ion reach the collector?

A. v > √2Bq/m
B. v < √2Bq/m
C. v > dBq/m
D. v < dBq/m

Kindly, tell me how to solve this question, please.

Thank you.
